Washington D.C. high school and middle school students now need a DC One Card to ride the city’s transit system. The card is a single ID card that gives students access to most D.C. government programs and facilities, including recreation centers, libraries, and the Metro.

The new rule went into effect Jan. 1 and students should have automatically received the card at their school.

If students don’t have a DC One Card, they should contact their school immediately. The same requirement will also apply to all K-5 schools and all educational campuses beginning Jan.16.

In addition, students or parents can apply online for the school transit subsidy, which provides reduced fares for District students who use Metrobus, Metrorail or the DC Circulator to travel to and from school.
